There are racial and ethnic differences in Blood type and composition.
We display these differences, in chart form, to show differences,
purities and migration. The ABO Blood group system was discovered in
1901 and since it is of major importance in medicine, samples have been
diligently collected from the most remote of people groups for a
century. Of no other human characteristic is so much data available.
Most populations have migrated and mixed. Unfortunately the reliability
of the Blood data for assessing relationships between population groups
is very limited. This is mostly due to the lack of availability and
interchange of this important data. As the chart below reveals, the
frequency and purity of the four main ABO Blood groups varies in
populations throughout the world. Great variation occurs in different
groups within a given country; even a small country, as one ethnic group
mixes, or not, with another. Blood type purity depends on migration,
disease, interrelational-reproductive opportunity, traditions and
customs, geography and the initial Blood type assigned.

Publishing the ethnic
differences in Blood type and the racial differences in Blood type is
not, in the present-day world, considered to be politically correct. We
compile and maintain this database through and thanks to, often times,
reliable, confidential sources. Every Blood gathering entity in the
world must gather this information to stay in business, but almost every
one of them is afraid to publish the racial and ethnic differences in
Blood type, given the emotionally charged political climate.

For example, early European races
are characterized by a very low type B frequency, and a relatively high
type A frequency while the Asiatic races are characterized by a high
frequency of types A and B. The following chart does not consider Rh
factor and may vary in specific regions. It is also different for some
very particular racial or ethnic groups. We have highlighted interesting
pure anomalies. We read from time to time that there are certain racial
groups that are more susceptible to one Blood disease or rare Blood
disease, Blood disorder or Blood inclusion than others. This information
could be life-saving, if you are a member of that group.

Rare blood types can cause Blood supply problems
for unprepared Blood banks and hospitals. For example, the rare Blood
type Duffy-negative Blood, occurs much more frequently in people of
African ancestry. The relatively rarity of this rare Blood type in the
rest of the North-American population can result in a shortage of that
rare Blood type for patients of African ethnicity, in need of a Blood
transfusion. Keep in mind, if you have a rare Blood type, there may be
some risk in traveling to parts of the world where your rare Blood type
may be in short supply. Knowledge of ABO Blood type frequency can be
life saving information. Blood

The frequency with which
Blood types are observed is determined by the frequency with which the
three alleles of the ABO gene are found in different parts of the world.
Variation in this allele frequency of the ABO gene reflects the social
tendency of populations to marry and reproduce within their national,
regional, or ethnic group. As people throughout the world intermingle to
a greater degree, the distribution of the different Blood types will
continue to become more uniform. Red cell antigens are the pheno-typical
expression of our inherited genes. One of the most common questions that
we get is about the the ethnic and racial distribution of human Blood
groups. In response, following here is our collection of basic ABO Blood
group data, sorted by people groups.

One note; we do not
consider the very small percentage of individuals who inherit unusual
combinations of "minor" antigens. Everyone carries substances on their
red Blood cells, called antigens. In addition to the well known ABO
classified groupings, and Rh factor, there are over 260 "minor" antigens
that have been identified. These antigens may appear in varying
combinations. The presence or absence of these specific "minor" antigens
single out that particular Blood type as being "rare." All Blood types
are inherited and therefore certain rare Blood combinations are more
common in specific ethnic and racial groups. We review this subject HERE. Discount

Pharmacy shelves are stocked with do-it-yourself home tests for
Blood glucose, Blood cholesterol paternity tests and pregnancy
tests. OraSure Technologies Inc., makes and sells a 20-minute,
at-home test that screens for two HIV strains using a swab
device that tests saliva, awaiting the FDA.

There is precise and
up-to-date data available. These racial and ethnic Blood typing and
population migration statistics are important in modern medicine for
many reasons. The overriding problem in obtaining and publishing this
information in the United States, and to a slightly lesser extent in
Western Europe, is political correctness. It is not nice to talk about
the ways that I may be different from you!

This data has some holes in
it; there are national and/or ethic groups whose statistics are not

A Word about Blood-related DNA Genealogy and Anthropological Sampling
- The relatively new science of DNA research applied to full-blooded,
indigenous populations from around the world has led to the discovery
and documentation of genetic markers that are unique to populations,
ethnicity and/or deep ancestral migration patterns. The markers having
very specific modes of inheritance, which are relatively unique to
specific populations, are used, among other things, to assess ancestral
and kinship probabilities. The following chart considers only these
full-blooded, indigenous groups.
